Z30 is better than z10 but the price of the z30 is really too high.
I like my BlackBerry very much but at z30 price you can choose nice android phones which have very nice speakers,display and are faster.
Or else you can wait till BlackBerry makes a new all touch device. They will be launching BlackBerry Rio soon. It's a small upgrade from z10 because that has bigger battery, larger screen.

Hope they they change the processor. Snapdragon 600 will be very good.

I'm very sensitive when it comes to screen quality, and the Z30's screen is an older type of AMOLED (think Galaxy S2) with pretty terrible color reproduction. Really noticeable when you put them side by side.

BTW: It's not an issue with AMOLED per se. Compared to my girlfriend's Lumia 930's SAMOLED screen, the Z30 doesn't stand a chance.

There is a very small difference in the ppi density. Now from where did lumia 930 come from? That is like 2014 and a very high- end device . Z30 came in 2013. Z10 is slow and has a bad battery, small screen and a heat up problem. I know about 20-24 people with these problems.
